Smaller, simpler database vs. the dominant all-in-one platform — most teams should just use Apollo.
Adapt.io and Apollo.io both sell access to B2B contact databases, but they are in different weight classes. Adapt has 150M+ contacts, a Chrome extension for LinkedIn prospecting, and CRM sync. Apollo has 275M+ contacts, a built-in sequencer, email verification, enrichment, intent data, and a free tier that starts before you pay anything. If your team needs a clean contact database and nothing else, Adapt is serviceable. If your team needs data plus an outreach motion, Apollo is hard to argue against.
Database size and data quality
Apollo's 275M+ contact database is roughly 80% larger than Adapt's 150M+. More importantly, Apollo invests heavily in data freshness — contacts are verified against live web signals, LinkedIn activity, and email deliverability checks. Adapt's database is smaller and the refresh cadence is less transparent. For teams prospecting deep into niche verticals or targeting senior executives at specific companies, Apollo's broader coverage means fewer gaps. Adapt's data is adequate for high-volume, lower-precision prospecting but you will notice the ceiling faster.
Platform depth
Adapt is a data tool. You search, find contacts, export or sync to CRM, and move on. That is the entire product. Apollo is a platform — it includes a sequencer, email and phone finder, enrichment, AI-generated email drafts, LinkedIn integration, intent data, buying signals, and analytics. The additional surface area is not just feature bloat — for teams that want their data and outreach motion in one place, Apollo eliminates tool sprawl. The tradeoff is complexity: Apollo takes longer to configure and has more decisions to make upfront.
Pricing and free tier
Apollo has a free tier that gives you 50 email credits per month before you pay anything — useful for small teams doing targeted outreach or for evaluating data quality before committing. Paid plans run $49/month (Basic) to $119/month (Professional) per user. Adapt has no free tier and starts at roughly $49-149/month depending on volume. For teams already in the market, Apollo's combination of more data, more features, and a free entry point makes the price comparison straightforward.

The verdict
Apollo for most teams. The database is larger, the platform is more capable, the free tier lets you validate before you buy, and the pricing is comparable. The only reason to choose Adapt over Apollo is if you specifically want a minimal contact database tool with no platform around it — some teams prefer that simplicity. But for any team running an outbound motion that needs both data and sequencing, Apollo eliminates a tool and gives you more of both.
Is Adapt's data good enough for serious outbound?
Adapt's data quality is adequate for outbound prospecting, particularly for mid-market targets. The 150M contact database covers most use cases. Where you notice gaps is in senior executive contacts at specific companies and very niche verticals where Apollo's additional 125M+ contacts provide meaningfully better coverage. If you are running high-volume outbound to broad ICPs, Adapt works. If you are running precision account-based outreach to a short list of target companies, Apollo's depth is worth it.
Does Apollo replace dedicated email verification tools like BounceBan or NeverBounce?
Apollo's built-in email verification reduces bounce rates but does not fully replace dedicated verification tools for campaigns where deliverability is critical. Apollo's verification is useful for initial filtering, but for campaigns sending hundreds of emails per day across multiple mailboxes, running final verification through a dedicated tool like BounceBan or ZeroBounce before push is still best practice. Apollo catches the obvious bad emails. The dedicated tools catch the risky ones.
Can I use Adapt and Apollo together?
Some teams use Adapt's Chrome extension for quick LinkedIn prospecting while using Apollo's broader database for bulk searches. This is overkill for most teams — Apollo's Chrome extension does the same thing. The more common pattern is evaluating both and choosing one. Adapt has no meaningful capability that Apollo does not also have.
